Patented Aug. 15, 1911.

Application filed March 18, 1910, Serial No. 550,289. Renewed July 12,1911.' Serial No. 638,214.

- To all whom it may concern:

Be it known that I, KNUT O. BERVEN, a citizen of the United States,residing at Hodges, in the county of Dawson, State of Montana, haveinvented a new and useful Improvement in Furrow-Guides, of which thefollowing is a specification.

This invention relates to improvements in furrow guides for attachmentto plows and like implements; and an object of this invention is toprovide a furrow guide which will prevent the soil turned in the plowingof one furrow from overlapping the soil just turned in plowing thepreceding furrow, whereby a smooth even surface is produced over theentire plowed field or area and the necessity of the customary crushingand rolling is avoided.

In the drawings illustrating the principle of this invention and thebest mode now known to me of applying that principle, Figure 1 is a planview of a plow equipped with my new furrow guide; Fig. 2 is a sideelevation of what is shown in Fig. 1; and Fig. 3 is a fragmentary detailwhich illustrates the mounting of the inner end of the connecting rod.

The plow may be of any ordinary type and, as shown in the drawings,consists of the plowbeam a, the handles 6, and the plowshare 0 having amoldboard d. The front end of the guideboard e is provided with abracket f bolted thereto and formed with a hole In the latter isinserted one end of the bent connecting rod 9 the other end of which isheld in its adjusted position in the bracket h by the screw-rod i. Thebracket h is fastened to the lower face of the plowbeam by the bolts it,between the heads of which and the top of the plowbeam is interposed awasher plate h. About the middle of the upper edge of the guideboard eis fastened a bracket 7' through a hole in which passes a rod 70 one endof which is mounted in the moldboard d and the other end of which isthreaded to engage a nut m. Between the latter and the bracket j isinterposed a piece of pipe or sleeve 11; and between the bracket and thecollar 0 there is interposed a coil spring 77 mounted on the rod 70. Thespring p tends to hold the guideboard e away from the moldboard d.

It will be obvious that the guideboard may be adjusted with respect tothe moldboard. Further, the spring p permits the guideboard to yield onthe rod 70 and thereby prevents breakage of the parts. Manifestly theguideboard may turn on the bent end of the connecting-rod g and mayslide on the rod is.

I claim:

The combination with a plow having a plowshare formed with a moldboard;of a guideboard for preventing the overlapping of the turned soil; a rodwhich connects said guideboard and plow, said guideboard being pivotallymounted on said rod; a rod one end of which is mounted in said moldboard and on which is slidably mounted said guideboard; and a springinterposed on the last named rod between said moldboard and guideboard.
